and a voltage rating of 250 V. Branch circuit protection must be provided in
the auxiliary power supply wiring to the IED, and if necessary it must be possible
to disconnect manually from the power supply. Fuse or circuit breaker up to 6 A
and 250 V should be close to the equipment.
Ensure that the IED is earthed before starting it.

2. The LCD lights up and
starting...
is displayed.
3. The main menu is displayed. A final steady green Ready LED indicates a
successful start-up of the device.
If the self supervision of the IED detects a diagnostic error during the start-up
process, the green Ready LED flashes. Further information on the error may be
visible on the local HMI under
Main menu/Diagnostics/IED status/General
